Electronic device housing

Abstract

An electronic device housing includes an outer casing, a microphone, and a recess in the outer casing proximate to the microphone. A base of the recess has a first adhesive portion and an adjacent first non-adhesive portion, and a hole is defined in the first non-adhesive portion and the recess. The hole and the recess define an acoustic pathway for sound external to the outer casing to reach the microphone. The first adhesive portion and the first non-adhesive portion have different shapes.

What is claimed is: 
     
       1. An electronic device housing comprising:
 an outer casing; 
 a dust-proof net; 
 a microphone; 
 a recess in the outer casing proximate to the microphone; 
 a base of the recess having a first adhesive portion and an adjacent first non-adhesive portion; and 
 a hole in the first non-adhesive portion and the recess, the hole and the recess defining an acoustic pathway for sound external to the outer casing to reach the microphone; 
 wherein the first adhesive portion and the first non-adhesive portion have different shapes; and 
 wherein the dust-proof net is mounted on the recess and has a same shape with the recess, and the dust-proof net comprises a second adhesive portion and a second non-adhesive portion connected to the second adhesive portion. 
 
     
     
       2. The electronic device housing of  claim 1 , wherein a shape of the first adhesive portion is non-symmetrical. 
     
     
       3. The electronic device housing of  claim 1 , wherein a shape of the first non-adhesive portion is non-symmetrical. 
     
     
       4. The electronic device housing of  claim 1 , wherein the electronic device housing comprises a microphone hole, and the microphone hole comprises a first microphone hole and a second microphone hole opposite to the first microphone hole; each of the first microphone hole and the second microphone hole comprises the recess and the hole. 
     
     
       5. The electronic device housing of  claim 4 , wherein the holes of the first microphone hole and the second microphone hole are defined at the same side of corresponding first adhesive portions. 
     
     
       6. The electronic device housing of  claim 4 ,
 wherein the outer casing further comprises a bottom wall and a side wall, and the side wall is bent and extends from periphery of the bottom wall; and 
 wherein the first microphone hole is defined at one end portion of the bottom wall, and the second microphone hole is defined in the side wall and adjacent to the first microphone hole. 
 
     
     
       7. The electronic device housing of  claim 1 , wherein the electronic device housing further comprises a double sided adhesive, the second adhesive portion is attached to the first adhesive portion through the double sided adhesive, and second non-adhesive portion overlaps with the first non-adhesive portion and the hole. 
     
     
       8. An electronic device housing comprising:
 an outer casing; 
 a microphone; 
 a recess in the outer casing proximate to the microphone; 
 a base of the recess having a first adhesive portion and an adjacent first non-adhesive portion; and 
 a hole in the first non-adhesive portion and the recess, the hole and the recess defining an acoustic pathway for sound external to the outer casing to reach the microphone; 
 wherein the first adhesive portion and the first non-adhesive portion have different shapes; 
 wherein the electronic device housing defines a microphone hole, the microphone hole comprises a first microphone hole and a second microphone hole opposite to the first microphone hole, and each of the first microphone hole and the second microphone hole comprises the recess and the hole; 
 wherein the outer casing further comprises a bottom wall and a side wall, and the side wall is bent and extends from periphery of the bottom wall; and 
 wherein the first microphone hole is defined at one end portion of the bottom wall, and the second microphone hole is defined in the side wall and adjacent to the first microphone hole. 
 
     
     
       9. The electronic device housing of  claim 8 , wherein a shape of the first adhesive portion is non-symmetrical. 
     
     
       10. The electronic device housing of  claim 8 , wherein a shape of the first non-adhesive portion is non-symmetrical. 
     
     
       11. The electronic device housing of  claim 8 , wherein the holes of the first microphone hole and the second microphone hole are defined at the same side of corresponding first adhesive portions. 
     
     
       12. The electronic device housing of  claim 8 , wherein the electronic device housing further comprises a dust-proof net, and the dust-proof net is mounted on the recess and has a same shape with the recess. 
     
     
       13. The electronic device housing of  claim 12 , wherein the dust-proof net comprises a second adhesive portion and a second non-adhesive portion connected to the second adhesive portion. 
     
     
       14. The electronic device housing of  claim 13 , wherein the electronic device housing further comprises a double sided adhesive, the second adhesive portion is attached to the first adhesive portion through the double sided adhesive, and second non-adhesive portion overlaps with the first non-adhesive portion and the hole.
